DRIVING-GEARING FOR UPRIGHT DRILLS.

To all whom it may concern:

Be it known that t, ALuER'r E. NEWTON,

a citizen of thel'nitcd States, residing at Worcester, in the county ofWorcester and State of Massachusetts, have invented a new and usefull)ri ring-Gearing for Upright Drills, ofwhich the following is aspecification.

. his invention relates to that class of machilie which are known asupright drills or drill presses.

The especial object of this invention is to I provide an upright drillhaying strong, slutple and easily controlled driving connections whichwill give a large number of speed changes, and to provide a. positivelylocked driving connection for the drill spindle when the same is beingoperated atlow speeds.

To these ends, this invention consists of the parts and combinations ofparts as hereinafter described and more particularly specification.

F In the accompanying three sheets of drawings, Figural is a side\l(*\\' of an upright, drill constructed according to this invention.Fig. 2 is a. transverse sectional view of the change speed gearboxtherefor. Fig; 3 is a detail View of the conne tions opcratedhy our ofthe change speed handles. Fig. 4 is a sectional view of the driving,train tit the top of the drill column or upright. Fig. 5 is adiegrsmmatio view showing positions of the handles for ditl'erent speedchanges, and Fig. 6 is a detail view of one of the friction clutches. i

In the ordinary form of upright drills which are now used, changed ofspeed are ordinarily se ured by the us of cone driving pulleys, whichform in etl'ect- 9. primary speed changing mechanism and, in some casesalso, by combining therewith a set of hack gems to act: as a secondaryspeed charging mechanism.

In an upright drill constructed according to this invention, the primaryspec-d changing mechanism consists of the change speed gear box havingtrains of gearing therein, which preferably give eight ditl'crcnt speedchanges mid the secondary speed changing mechanism of the drillpreferably cmisists of :1. novel arrangement of back gearing in whichthe geais are in constant mcsh and in which the c utcli hNllilttI, l1)means it which the drill spindle will ii" driven through f'i tionul con-U s- TE striir ss PATENT OFFICE;

- In a com te drill constructed according 6 to this im" 1CD. the portsare preferably combined to secure sixteen speed c stages.
